Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- ...

Astronomers have caught a cosmic explosion doing something it was never supposed to do, firing off three powerful gamma-ray bursts from the same source within hours. The triple outburst is forcing ...

Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...

A peculiar cosmic explosion first detected by NASA’s Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth. By Laura Baisas Published Jun 23, 2023 9:00 AM EDT Get the Popular Science daily ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

What is the nature of dark energy, a recently discovered dominant constituent of the universe today? Is expansion-accelerating dark energy an intrinsic property of space-time itself or rather a field ...
